I have some code that is supposed to capture data from an ethernet adapter. I am using the following steps to get the data (after determining the name of the device in the format: "rpcap://\Device\NPF_{0C5[...]C89}"):

This is probably Npcap issue #178, which is fixed in Npcap 0.9992, so it should also be fixed in the current release (0.9994 as of the time I'm writing this). Upgrade your Npcap installation.

How to use add_packet_field in a Wireshark Lua dissector?

Asked 2020-Jul-08 at 21:49

I am stumbling my way through writing a dissector for our custom protocol in Lua. While I have basic field extraction working, many of our fields have scale factors associated with them. I'd like to present the scaled value in addition to the raw extracted value.

It seems to me tree_item:add_packet_field is tailor-made for this purpose. Except I can't get it to work.

I found Mika's blog incredibly helpful, and followed his pattern for breaking my dissector into different files, etc. That's all working.

Given a packet type "my_packet", I have a 14-bit signed integer "AOA" that I can extract just fine

Looking at the try_add_packet_field() source code, only certain FT_ types are supported, namely:

FT_BYTES
FT_UINT_BYTES
FT_OID
FT_REL_OID
FT_SYSTEM_ID
FT_ABSOLUTE_TIME
FT_RELATIVE_TIME

None of the other FT_ types are supported [yet], including FT_UINT16, which is the one you're interested in here, i.e., anything else just needs to be done the old fashioned way.

If you'd like this to be implemented, I'd suggest filing a Wireshark enhancement bug request for this over at the Wireshark Bug Tracker.

QUESTION

Does sniffing in loopback capture outside traffic?

Asked 2020-May-18 at 05:20

i have a game server running on some port. I learned to sniff packets on loopback. So if i connect to it from same computer, the packets are captured.

But somebody can connect from other computer and the packet will not be sniffed.

The packets from some computer must pass through one of my interfaces. So should i sniff on that interface too inorder to get packets coming from both my computer and other computers?

Here is my program

Yes, you use do that - or, if you're running on Linux, you can capture on the "any" device, which should capture traffic on all interfaces.

Answered 2020-Feb-06 at 15:39

I was able to compile this by moving the SDK folders from C:\WdpPack to my C:\User folder. I am not so familiar with Windows, so I am not sure why this works, maybe something to do with permissions?

Update:

After running perl Makefile.PL, running gmake to compile the module fails with errors:
